PIGKER HOLDER Filed Feb. 25. 1928 Patented Dec. 3, 1929 rArn WALTER A.SAA'IMAN, OF ROSLYN, "BENNSYLVANIA' PICKER HOLDER Application filedFebruary 23, 1928.

My invention relates to gluing mechanism such as is used for gluingwraps, etc., in box manufacture.

The purpose of my invention is to facilitate 5 the replacement of thepickers by which the wraps are withdrawn from the glue applylng roll.

A further purpose is to provide the picker holders with readilyseparable spring connection with the pickers so that by slight rotationof the picker holders the pickers can be withdrawn for examination andreturned or replaced by new pickers as desired.

A further purpose is to provide a partieular form of removableconnection between picker holders and pickers held thereby.

I have preferred to illustrate my invention by one form only, selectinga form which is practical, efficient, reliable and inexpensive 0 andwhich at the same time well illustrates the principles involved.

Figure l is a fragmentary side elevation, partly in section showing aglue applying roll, pickers engaging it and associated parts.

5 Figure 2 is a top plan view of part of the structure seen in Figure 1.

Figure 3 is a fragmentary enlarged section of a portion of Figure 1taken in a plane parallel to that of Figure 1.

0 Figure t is a fragmentary rear elevation of a portion of a supportingrod, a picker holder and a picker such as are seen in the other figures.

In the drawings similar numerals indicate 35 like parts.

In the drawings I have illustrated a feed roll 5, stripper fingers 6,guide 7 and glue drip cup 8, comprising a portion of the mechanism usedin feeding wraps to a glue-apply- 10 ing roll 9. The glue is applied tothe glue applying roll by an intermediate roll 10 and the quantity ofglue upon the glue-applying roll is determined at the same time that thesurface of the glue is smoothed by a doc- 45 t-or roll 11 moving in theopposite direction from the direction of rotation of the glueapplyingroll. A conveyor pulley 12 and conveyor 13 are also shown. As thus fardescribed these are all old and are illustrated 59 here merely as aconventional form, one of the figures about pivot pins Serial No.256,452.

many settings with which my invention may be used. The only essential sofar is that there shall be a glue-applying roll upon which glue isdeposited and from which wraps are to be picked.

The picker 1d is spring pressed against the glue-applying roll 9 so thatthe point 15 of the picker and the adjoining picker edge will separatethe wraps from the glueapplying roll.

As required by law I have illustrated the best form of picker holdersand pickers known to me but am satisfied that many other forms of myinvention would operate suc cessfully and satisfactorily.

As illustrated, the picker holders 16 comprise bodies 17, bored at 18 tofit upon transverse supporting rods 19 and held upon the rods inselected position longitudinally of the rods and also angularly aboutthem by set screws 20. I

The picker holders 16 are slotted at 21 to receive the pickers 14 andare additionally bored at 22 to receive springs 23 by which the pickersare held to their duty. The springs press against the bottoms 24 of theboresat one end and against heels 25 upon the pickers at the oppositeends so as to tend to turn the pickers in clockwise direction in 26extending transversely of the slots 21.

Each picker is slotted or notched at one edge as at 2? much on the orderof a keyhole slot, terminating in a bearing surface 28 adapted torestupon and turn about a pivot pin 26.

The upper ends of the pickers are rounded at 29 so that when the pickerholders have been loosened and rotated in counter-clockwise directionfrom the positions shown in Figures 1 and 8, the pickers can be turnedin clockwise direction so as to permit withdrawal of the pickers byrelative movement of the pickers and pivot pins along slots 27, havingthe effect of Withdrawing the picker pivot pins from the pickers throughslots 27. With normal spring compression the compression of the springs24: will be released before the withdrawal of the pickers from about thepivot pins.

I believe that I am the first to provide for removability 0tspring-pressed pickers from their picker holders without removal oftheir picker holders from their supports, and correspondingly intend toclaim this subject matter broadly.

In view of my invention and disclosure variations and modifications tomeet individual Whim or particular need will doubtless become evident toothers skilled in the art, to obtain part or all of the benefits of myinvention without copying the structure shown, and I, therefore, claimall such in so far as they fall Within the reasonable spirit and scopeof my invention.

Having thus described my invention, What I claim as new and desire tosecure by Letters Patent is 1. A picker holder having an opening thereinfor mounting upon a support, means for securing the holder in angularlyadjusted position upon the support, a pivot pin upon the holder, apicker mounted upon the pivot pin and slotted to permit removal from thepin by movement in the planes of the picker and spring means for holdingthe picker to its duty, tending to turn it about the pivot pin.

2. A picker holder apertured to receive a support, a screw adapted to iithe body in angularly adjust-ed position, a picker adapted to fit in aslot in the picker holder and having a lateral opening from the edgeterminating in a hearing, a pivotpin across the slot, upon which pin thebearing is adapted to lit and a spring engaging the picker toresiliently tend to turn it about the pivot pin.

3. A picker holder adapted to be mounted upon and held to a support andhaving a slot at one end, a pivot pin across the slot, a picker havingan opening at one edge and a hearing communicating with the openingadapted to rest upon the pivot pin and spring means tending to turn thepicker about the pin.
